PUTTY-KNIFE.

Specication of Letters Patent.

Patented June 1, 1910.

Application led August 18, 1909. Serial N o. 513,487.

To all whom 'it may concern:

Be it known that I, ANDREW J. COMPTON, a citizen of the United States,residing at Trenton,- in the county of Mercer and State of New Jersey,have invented new and useful Improvements in Putty-Knives, of which thefollowing is a specification.

This invention relates to putty knives for use of glaziers and it hasfor its object to provide a putty knife of simple and improvedconstruction in the blade of which shall be combined a plurality oftools for various purposes.

Further objects of the invention are to simplify and improvetheconstruction and operation of this class of devices.

IVith these and other ends in View which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention; it being however, understood` that no limitationis necessarily made to the recise structural details therein exhibitedut that changes, alterations and modifications within the scope of theinvention may be resorted to when desired.

In the drawing: Figure 1 is a side view of a putty knife constructed 'inaccordance with the lnvention. Fig. 2 is an edge view of the same. Fig.3 is a transversesectional view of the blade taken on the planeindicated by the line 3-3 in Fig. 1.

Corresponding parts in the'severalviews are denoted by like charactersof reference.

The present invention constitutes an improvement on the putty knife forwhich Letters Patent of the United States were granted to me on the 27thday of July, 1909, No. 929,194.

The blade 5l of the present invention is suitably connected with ahandle 6, and said blade is provided with outwardly diverging side edges7-8 and with a front edge 9 which 1s formed approximately at rightangles to the longitudinal axis of the blade.

' Upon the side edge? adjacent to the front end 9 there is formed alaterally extending V-shaped projection 10 having a cutting edge l11adjacent to the edge 7 of the blade;

the opposite side 8 of the blade is provided with a trapezoidal recess12, the lower edge 13 of which whereby is meant the edge most closely ajacent to the handle) is approximately parallel to and is disposed 1napproximate alinement with thecutting edge 11 ofthe member 10. Thevupper ed e 14 of the recess 12 is approximately para lel to theedge ofthe blade. The portion of the side edge of the blade which-connects theouter extremity of the edge 14 with the ed e 9 is disposed at right anles to both t e side edges so that a stri 'ng face 15 will be formed.

In practice the sharp pointed member 10 may be utilized as a can openerfor the purpose of opening paint cans, and it also constitutes anextremely useful device for the purpose of removing old utty fromframes,

window sash and the like; when utilized for the latter purpose, thelower edge 13 of the recess 12 which is approximatel parallel to and inalinement with the cutting edge 11 may be effectively struck with ahammer or similar tool ,for the purpose of facilitatv ing the removal ofold putty, especially when the latter has become too old to be readilyremoved. The edge 9 of the blade may be utilized as a scraper and alsofor the purse of applying putty in the usual well own manner; andtheedge 15 constitutes a striking face which may be very effectively usedfor the purpose of driving glaziers points. It will thus be seen thatthe device constitutes a combination tool which will be found vextremelyuseful .and serviceable for a varietyV of purposes and it will also beseen that' the improvement is of such simplicity.

that it may be manufactured at an expense not necessarily exceeding thatof an oldfashioned put-ty knife.

Having thus described the invention, what is claimed is- 1. A utty knifeincluding a blade provided a jacent to its outer edge with a V- shapedlateral extension and provided at its opposite edge with a recess, thelower ed e of which is approximately parallel to t e lower edge of theV-sha e extension.

2. A putty knife inc uding a blade hav ing a Vshaped lateral extensionadjacent to its outer edve and provided at its o posite side edge with atrapezoidal recess; t e por- 9 at the upper or outer end tion of theside ed e between said recess and tween said recess and the outer edgeof tbe the outer edge of t e blade being disposed at right angles to thelatter.

3. A putty knife including a blade having divergent side edges, an outeredge disposed at right angles to the blade, and a' V shaped lateralextension adjacent to the outer edge; the o osite Side edge of the bladebeing providlg with a trapezoidal recess, and the portion of the si eedge beblade being disposed at right angles to the latter.

In testlmony whereof I ax my signature 1n presence of two witnesses.

ANDREW J. COMPTON.
